Routine design When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art. The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.

Joiners A Photograph by David Hockney www.hockney.com Show image 0 Show image 1 In the early 1980’s, English painter David Hockney began creating intricate photo collages that he called “joiners”. His earlier collages consisted of grid-like compositions made up of polaroid photographs. He then switched to photo lab processed 35mm photographs and created collages that took on a shape of their own, creating abstract representations of the scenes he had photographed. The varied exposures of the individual photographs that make up each collage give each work a fluidity and movement that otherwise might not be found. Start drawing, then put the box around it
